Weak at Less mature observability ecosystem than RabbitMQ; some advanced patterns require deeper NATS-specific knowledge.

Replaces these SaaS
- Amazon SQS · Message queue / async messaging
`docker run -p 4222:4222 -p 8222:8222 nats:latest -js -m 8222`. Client migration: NATS clients exist for 40+ languages; the JetStream API gives you durable streams + consumers (the SQS-equivalent). Map an SQS queue to a JetStream stream with a single durable consumer. DLQ via `MaxDeliver` + `republish` to a separate stream.
